Research guide for gradual escalation dosing and reconstitution procedures for GHRP-2, a synthetic hexapeptide investigated for growth hormone release stimulation.
Quickstart Highlights
GHRP-2, or pralmorelin, functions as a synthetic hexapeptide that stimulates the ghrelin/GHS receptor on pituitary somatotroph cells to trigger growth hormone release. Operating independently of the typical GH-releasing hormone pathway makes it valuable for research into body composition and recovery support.
Reconstitute: Add 3.0 mL bacteriostatic water → concentration for daily dosing Weekly dosing schedule: 100 mcg → 150 mcg → 200 mcg → 250-300 mcg over 12 weeks Easy measuring: Standard U-100 insulin syringe measurement Storage: Lyophilized: −20 °C (−4 °F), dry conditions; Reconstituted: 2–8 °C, use within 28 days
Dosing & Reconstitution Guide
Standard Once-Daily Approach (3mL reconstitution)
Daily Subcutaneous Protocol (3 mL reconstitution)
Duration Daily Dose Syringe Units Volume Weeks 1–2 100 mcg 3 units 0.03 mL Weeks 3–4 150 mcg 4.5 units 0.045 mL Weeks 5–8 200 mcg 6 units 0.06 mL Weeks 9–12 250–300 mcg 7.5–9 units 0.075–0.09 mL
Administration: Single daily subcutaneous injection at bedtime on an empty stomach (2–3 hours after eating).
Reconstitution Steps
Draw 3.0 mL bacteriostatic water with sterile syringe Inject slowly along vial wall; avoid foaming Gently swirl/roll until dissolved (do not shake) Label with date; refrigerate at 2–8 °C, use within 28 days
Result: Standard reconstitution concentration for daily administration
Storage Guidelines
Lyophilized: −20 °C (−4 °F), dry/dark conditions Reconstituted: 2–8 °C (35.6–46.4 °F); do NOT freeze Shelf life: 28 days post-reconstitution
Key Administration Notes
Rotate injection sites to prevent lipohypertrophy Gastrointestinal effects common initially; titration minimizes them Document weekly dose, date, and injection site Use sterile syringes; dispose in sharps container Allow vials to reach room temperature before opening
